The water collecting container 20 according to one embodiment of the present invention is composed of: a container 70 mounted at the container mounting portion 22 formed at the body 10 and having a space for storing water; a cover 74 mounted at an opened upper surface of the container 70 and having an outlet 72 for exhausting air inside the container 70; a division plate 80 for dividing the inside of the container 70 into a first chamber 76 and a second chamber 78, for introducing water stored in the second chamber 78 to the first chamber 76 when the water inside the second chamber 78 is more than a certain level; and a water exhaustion preventing unit 84 mounted at an upper surface of the division plate 80 and arranged at the first chamber 76, for preventing water stored in the container 70 from being exhausted through the outlet 72.

The container 70 is formed as a cylindrical shape having an opened upper surface, and has a handgrip 82 at an outer side surface thereof. An inlet 86 connected to the water suction hose 50 and through which water is introduced is formed at a lower side of the container 70.

A guide passage 88 for moving water introduced into the inlet 86 to an upper portion of the container 70 and then introducing the water of the upper portion of the container 70 into the container 70 is formed at an inner side of the container 70.

The guide passage 88 is formed by a partition wall 90 formed in the container 70 in a vertical direction, and a lower side of the guide passage 88 is connected to the inlet 86. An entrance 92 formed as one side of the partition wall 90 is cut and through which water that has flowed up along the guide passage 88 is introduced into the container 70 is formed at an upper end of the guide passage 88.

The guide passage 88 prevents contaminated water introduced into the container 70 through the inlet 86 from backward flowing to the suction nozzle 14.

The division plate 80 is composed of: a first plate 94 arranged in the container 70 in a horizontal direction and formed as an arc shape; a second plate 96 extended from one side surface of the first plate 94 in a vertical direction; and a third plate 98 extended from another side surface of the first plate 94 in a vertical direction and integrally connected to a lateral surface of the second plate 96, thereby forming the first chamber 76.

A passage 68 for introducing water stored in the second chamber 78 to the first chamber 76 when water stored in the second chamber 78 reaches a certain level is formed at an upper surface of the third plate 98.

The water exhaustion preventing unit 84 is composed of: a floater housing 100 positioned in the first chamber 76, mounted at an upper surface of the first plate 94 of the division plate 80, and connected to the outlet 72 formed at the cover 74; and a floater 102 mounted at the floater housing 100 to be movable up and down, for preventing water from being exhausted through the outlet 72 by blocking the outlet 72 by a buoyancy force when water reaches a certain level.

The water exhaustion preventing unit 84 is positioned in the container 70 to be inclined towards the front side of the body 10. That is, the water exhaustion preventing unit 84 is preferably positioned at an opposite side to a direction that the body 10 is inclined at the time of performing a cleaning.

Since the water exhaustion preventing unit 84 is arranged to be encompassed by the division plate 80, a mis-operation of the floater 102 due to sloshing of water stored in the second chamber 78 can be prevented at the time of performing a cleaning.

The cover 74 is composed of: a body 104 of a disc shape fittedly-coupled to an upper surface of the container 70; a tube connection portion 106 formed at the center of an upper surface of the body 104 and connected to an exhaustion tube 110 connected to the fan motor 24; a connection portion 108 formed as a ring shape towards a down direction from the outlet 72 formed at a lower surface of the body 104, and fittedly-coupled to the floater housing 100; and a guide chamber 120 formed at a lower side of the body 104, for connecting the outlet 72 and the tube connection portion 106 so that air exhausted through the outlet 72 can be guided to the tube connection portion 106.

A plate 112 is downwardly extended from the lower surface of the body 104 to encompass the outlet 72, and is in contact with the second plate 96 and the third plate 98 of the division plate 80, respectively.

An operation of the complex type cleaner according to the present invention will be explained as follows.

First, the operation of the complex type cleaner in a vacuum cleaning mode will be explained with reference to FIG. 2. The user mounts the dust collecting container 18 at the container mounting portion 22 of the body 10, and then operates the vacuum cleaning switch 28.

According to this, the fan motor 24 is operated to generate a suction force, and thereby dust and foreign materials on a floor or a carpet are sucked into the suction head 12 through the dust suction opening 32. At this time, the brush 36 mounted at the dust suction opening 32 is rotated, thereby brushing up dust and foreign materials on a floor or a carpet to the inner side of the suction head 12. The dust and foreign materials that have been sucked into the suction head 12 are introduced into the container 42 of the dust collecting container 18 through the suction hose 34. Then, the dust and foreign materials that have been sucked into the container 42 are filtered by the filter 46 and are collected in the container 42. At this time, only the air that has been purified while passing through the filter 46 is exhausted through the exhaust passage 48, and is exhausted to the outside via the fan motor 24.

Second, the operation of the complex type cleaner in a water cleaning mode will be explained with reference to FIG. 3. The user mounts the water collecting container 20 to the container mounting portion 22 of the body 10, and connects the inlet 86 of the water collecting container 20 to the suction nozzle 14 by the water suction hose 50. Then, the user operates the water cleaning switch 30 mounted at the body 10. According to this, the fan motor 24 is operated to generate a suction force, and at the same time, the pump 60 is operated to spray cleaning water to a floor or a carpet.

By a pumping force generated as the pump 60 is operated, the cleaning water stored in the water tank 56 is guided to the spray nozzle 62 through the cleaning water supply line 58. The spray nozzle 62 sprays the cleaning water to a floor or a carpet.

The brush 36 mounted in the suction head 12 rubs a region to be cleaned or a carpet on which cleaning water is sprayed while being rotated. By a suction force generated as the fan motor 24 is operated, water contaminated after completing the cleaning is sucked into the nozzle portion 52 of the suction nozzle 14.

Then, the contaminated water sucked into the nozzle portion 52 of the suction nozzle 52 is guided by the guide passage portion 54, and is introduced into the water collecting container 20 through the water suction hose 50.

The operation of the water collecting container 20 when water is introduced into the water collecting container 20 will be explained in more detail as follows.

Once water is introduced into the container 70 through the inlet 86, the water is guided to the upper side of the container 70 along the guide passage 88 and then is introduced into the second chamber 78 of the container 70 through the entrance 92 formed at the upper end of the guide passage 88.

When water is introduced into the second chamber 78 of the container 70, air inside the container 70 is exhausted to the outside via the fan motor 24 through the outlet 72 formed at the cover 74 and the exhaustion tube 110.

When a level of water introduced into the second chamber 78 of the container 70 is more than a certain level, the water stored in the second chamber 78 is introduced into the first chamber 76 through the plate 112 formed at the division plate 80. By a buoyancy force of the water introduced into the first chamber 76, the floater 102 floats up and blocks the outlet 72, thereby preventing water supplied into the container 70 from being exhausted to the outside.

Since the water exhaustion preventing unit 84 including the floater 102 is encompassed by the division plate 80 formed by the first plate 94, the second plate 96, and the third plate 98, the mis-operation of the floater 102 due to sloshing of the water stored in the container 70 during a cleaning operation can be prevented.

Effects of the complex type cleaner according to the present invention will be explained as follows.

In the complex type cleaner according to the present invention, a vacuum cleaning function for sucking dust and a water cleaning function for sucking water by spraying cleaning water to a region to be cleaned are realized in one cleaner, thereby reducing the cost, enhancing the user's convenience, and facilitating to store the cleaner.

Also, the inside of the container is divided into the first chamber and the second chamber and the water exhaustion preventing unit is installed at the second chamber, thereby preventing the mis-operation of the floater of the water exhaustion preventing unit due to sloshing of the water stored in the container during a cleaning operation.
